Following the initiation of an investigation, the Planning Director may require the
owner or operator of any use that may be in violation of performance standards to
submit, in a reasonable amount of time, such data and evidence as is needed by the
Planning Director to make an objective determination. Failure to submit data required
shall constitute grounds for revoking any previously issued approvals or permits and
ceasing of operations until the violation is remedied, as provided for in Section 8181-8 of this Chapter.
